-C AIIMEN forming part of Letters Patent No. 339,642, dated April 13,1886.

Application filed Scptemberfll, 1885. Serial No. 178,071. (No model.)

To all whom it may concern:

Be it known that I, Gnonen W. GRIFFIN,

of Franklin Falls, county of Mcrrimac, and

State of New Hampshire, have invented an Improvement in Fabrio-TurfingImplements, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to construct a hand-operated devicefor inserting rags or usual carpet-yarns into woven fabric to form apilc-as, i'orinstancc,in the making'of rugs, &c.-and is an improvementupon Letters Patent ol'the United States No. 246, 005 granted to me August 23,1881, to which reference may be had.

The invention consists, essentially, in the combination, with the needleand its co-operating pile-i nscrting iustrument,of mechanism,substantially as will be described, for operating the said needle andits pile-inserting instrument, the said mechanism being of suchconstruction as to be easily operated by hand.

Also, in the combination, with the needle and its cooperatingpile-inserting instrument, of feeding mechanism, substantially as willbe described, whereby the implement is caused to travel along over thesurface of the fabric forming the foundation, and through which the pileis being inserted.

The main supporting-bar, to which the actuating parts are attached, isbent at right angles, its forward end forming a prcsser-foot for theneedle and its cooperating pile-inserting instrument.

The feeding mechanism herein shown consists of a cam-block adjustablyattached to the main supportingbar, a projecting portion of the needlestriking the said cam-block as the needle enters the material, the saidcanrblock being of such shape that during the further movement of theneedle into, and while it is held by, the fabric in making its stitch,the supporting-bar and its attached presser-foot are moved laterallyfrom the needle a sufficient distance to come into position for the nextstitch, so that when the needle is withdrawn from the fabric andrestored to its normal position parallel with the supporting-bar bysuitable springs or otherwise the said needle will be in position forthe next stitch.

Figure 1 represents in front elevation an apparatus for-inserting pileinto woven fabric, and Fig. 2 a similar View, with the needle in theposition it will occupy when forced through the material and forward oroutward by the cam-block.

The main supporting-bar A, to which is attached the guide-frame ab c, isprovided with a hand-piece, B.

The guide-frame consists of the bearingblock a,pivoted to thesupportingbar A at a, and the auxiliary bearing-block I2,rigidlyconnected with the said bearing-block a by a rod, 0.

The needle (I, made tubular and having an eye, (2, is herein shown as inone piece with the necdlebar d", and fitted to slide freely in the saidbearing-blocks a b, the handle (1 being supplied to reciprocate the saidneedle when desired. I

The pile-inserting instrument, composed of a shank portion, 6, fitted toslide freely in the guideframe, is bent substantially at right angles atits forward end, as shown at a to form a shoulder or projection to beloosely engaged by a bifurcated arm, e, projecting from the needle-bar.

The pile-inserting instrument, composed of a flat piece of metal-,toextend forward through the tubular needle and grooved at its forwardend, is attached to the shank e. The rod 0 has pivoted within it a dog,0, having two oppositely-proj ecting teeth,2 3, the tooth 2 beingadapted to engage a notch, 4, cut in the side of the shank 0, while thetooth 3 is acted upon by a projection, 5, extending from the needlebar(1", the said dog being controlled by a flat spring, 10, secured to therod 0. Normally the tooth 2 of the dog is cut to protrude and bearagainst the shank e, the remaining parts of the apparatus being as shownin Fig. 1. As the needle, it having the pile-forming material placed inits eye (1, as in the patent referred to, is forced forward by thehandle d through the fabric, the arm 6, by its engagement with the shankc of the pile-inserting instrument, also carries the latter forward,with its point just in the rear of the point of the needle, and,arriving at their extreme positions through the fabric, the tooth2 ofthe IOC dog a or locking device engages the notch 4t of the shank 0,looks the pile-inserting instrument in its extreme position through the'fabric while the needle-bar is withdrawn, the pile-inserting instrumentremaining in its extreme position, holding the loop of pile until theneedle has reached its starting-p0int,when the projection 5 will strikethe tooth 3 of the dog 0 and, disengaging it from the projection 4-,permit the pile-inserting instrument to immediately return to its normalposition by the spiral spring f, connecting it with the bearingblock a,the return of the pile-insertinginstru ment leaving behind itthe loop ofpile, and the parts are ready to be operated for the insertion of a newloop. The supporting-bar A is bent at its forward end at rightangles, asat g, and is bifurcated to form a presscr-foot, between the forked endsof which the needle, with its cooperating pile-inserting instrument,passes, as in a sewing-machine.

The needle-bar has an inclined portion, (1 which, co-operating with acam-block, m, adjustably secured to the supporting-bar A by means of ascrew, m, in a slot, W, in the said bar, constitutes the feedingmechanism. The action of said inclined portion on the camblock after theentrance of the point of the needle into the fabric causes thepresser-foot to be moved upon or over the material a sufficient distanceto come into proper position for the next insertion of the nextpile-loop. When the needle is withdrawn from the fabric, it is restoredto its normal position, or parallel with the supporting-bar, by thespiral. spring 12, which connects the guide-frame with thesupporting-bar A.

It is obvious that the mechanism herein described for operating theneedle and pile-inserting instrument may be employed with equally goodresults with a flat or other needle.

I claim- 1. The supporting-bar, the guide-frame, the needle-bar, theneedle, andthe pile-inserting instrument attachedto the shank e, and thearm 6, connected to the needle-bar and en gaging the said shank to movethe pile-inserting instrument through the fabric, combined with thelocking device, substantially as described, to lock the pile-insertinginstrument in its extreme position through the fabric while the needlereturns, and with mechanism, substantially as described, for releasingsaid and the projection 5, to trip the said dog or locking device,substantially as and for the purpose described.

3. The guide-frame, the needle-bar provided with the incline, theneedle, and pile-inserting instrument, the shank e, and thesupporting-bar pivoted with relation to the guideframe, the cam-block m,cooperating with the needle-bar to move the supportingbar laterallywhile the needle is penetrating the material, substantially asdescribed.

4. The supporting-bar, its presser-foot, and needle and pile-insertinginstrument, combinedwith the pivoted supporting-frame carrying theneedle and pile-inserting instrument, and the cam-block, all as setforth.

5. The supporting-bar and its presser-foot, combined with a tubularneedle, and pile-inserting instrument moving within the tubular needle,both needle and pile-inserting instrument being pivotally connected withthe supporting-bar, and the cam-block for moving the supporting-barforward While the needle remains in the fabric being turfed,substantially as described.

6. In a machine for turfing fabric, the needle and pile-insertinginstrument, and a pivoted frame carrying the same, the cam to effect thefeeding of the material being turfed by the needle and pile-insertinginstrument, and the presser-foot to hold the material in place while thepile is being inserted, all substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

GEORGE \V. GRIFFIN.
